DOOR-CHECK.

t SPECIFICATION forming part of Letters Patent No. 469,825, dated MarchV1,1892.

Application led October 3, 1891. Serial No. 407,627. (No model.)

T0 all whom, t may concern:

Be it known that I, THOMAs D. MORRIS, of Seward, Seward county,Nebraska, have invented certain new and usefulImprovements inDoor-Checks, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, for-minga part hereof.

My invention relates to attachments to the doors of buildings andsimilar structures; and

the objects of my invention are to produce atportion of a closed doorwith my improved check applied thereto. Fig. 2 is a similar view ofthelower portion of an open door with-my said door-check applied thereto.Fig. 3 is a front elevation of the door-check on an enlarged scale. Fig.4 is a transverse vertical section of the same on the line 4 4 of Fig.In the said drawings, let l designate a door or similar structure and 2one of the hinges thereof.

3 designates a base or backing plate, which is of either the precisegeneral forms shown `or of any other suitable or preferred form,

and which is designed to be attached to the lower and outer corner of adoor by anysnitable number of screws 4 or equivalent devices.

5 designates an L-shaped slide, the lower part of the vertical arm ofwhich is conined.

loosely beneath a horizontal strap 6, which is either secured to thelower part of the backing-plate by screws 7 or corresponding rivets, orwhich is formed integrally with said backing or base plate. At the upperpart of its vertical arm this slide is formed with a vertical elongatedopening or slot 8, in which works a pin or projecting stud 9, which issecured to or formed upon the upper part of the backing-plate 3 and thehead or enlarged outer end'of which overlaps the margins of the slot oropening S and thus assists the strap 6 in maintaining the slide 5 inworking position. The outer edge of the lower rectangular arm of theslide 3 is formed with a transverse eye l0, through which extendsloosely the upper bar of an open U-shaped loop or link 1l. Between thelower ends of the arms of this loop is formed or rigidly secured acylindrical bar l2. This presser bar or foot is rigidly secured at itsends to the lower ends of the arms of loop ll, so that said foot or barcannot rotate, or said bar or foot may be formed integrally with thelower ends of said arms. The under surface of the bar or foot isroughened or serrated, as at 23, toinsure a firmer hold of the bar orfoot upon the Hoor or carpet. To the upper part of the backing or baseplate 3 is secured, as by a rivet 13, or in equivalent manner, the upperend of a leaf-spring 14, the lower end of which is secured, as by ascrew l5, to the lower part ot the vertical arm of the slide 5, the saidspring thus occcupying a vertical position. It will thus be seen thatwhen the door is opened the frictional contact of the bar 12 with thefloor or carpet will cause said bar to move inwardly toward the adjacentside of the door, carrying the link 1l with it and consequently raisingthe slide 5 and bowing the spring 14 Outward, as shown in dotted linesin Fig. 4. Consequently the door will be held open by the pressure ofthe spring. At the same time the door can be readily .moved to furtheropen it or to close it, the contact of the bar with the floor or carpetbeing only sufficiently iirin to prevent the door from being moved openor closed by drafts.

From the above description it will be seen that I have produced adoor-check which is simple, durable, and inexpensive in construction,and which operates to properly retain the door in any desired positionwithout preventing the door from being easily opened or closed whendesired.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is

l. An improved door-check comprising a base-plate designed to beattached tixedly to a door and provided at its lower part with a IOChorizontal guide-strap, an L-shaped slide having at its upper endalongitudinal slot or opening, a stud projecting from the upper part ofthe backing-plate and entering said slot or opening, a Verticalpresser-spring secured fixedly at its upper end to the upper part of thebacking-plate and similarly seen red at its lower end to the lower partof the slide, a loop pivotally secured to it at its-up.- per end to theouter end of the lower arm of the slide, and a presser foot or barcarried by the lower end of the loop, the lower part ot the upper arm ofthe slide passing freely beneath the guide-strap, and the presser-footserving by its eective changes of position to substantially as setforth.

2. An improved door-check comprising an axially-fixed presser bar orfoot of cylindrical form and having its lower surface only corrugated orrougncned, a loop or link to which the said presser-bar is xedlyattached, a carrier arranged to move vertically upon a door, fthe looporl'nk being attached to the lower part of the carrier, and apresser-spring opj erating upon the lower part of the carrier,substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS D. MORRIS.
